Custom GPTs vs ChatGPT Projects: When to Use Which

A Custom GPT is a packaged ChatGPT with a name, description, instructions, files, and optional API actions — and you can share its link. A Project is a private folder of chats with shared instructions and files. GPT = product. Project = workspace.

Some examples

• Custom GPT: 'Resume Reviewer' you can share with your whole class.
• Project: 'My College Essays' just for you.
• Custom GPT: 'D&D DM Helper' that anyone running a campaign can use.
• Project: 'My Calc 2 Homework' with your textbook attached, just for you.

Try it!

Think of one tool you'd want to share with friends. Sketch a Custom GPT for it (name, instructions, 1 file). Then think of one personal workspace you need — that's a Project.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain Custom GPT in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "Custom GPTs vs ChatGPT Projects: When to Use Which" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check Projects against a trusted source, teacher, adult, expert, or original document before you use it.
